Local Policy based routing checking origin DIDs & source IP

 

Hello Everybody

 

I'd like to explore the possibility of this implementation:

 

Several traffic source IP's (each one for a different costumer) are sending calls via a single SBC interface.

 

Each IP uses it's own certain number of DIDs (no DIDs are shared between source IPs).

 

The need here is that traffic must be filtered via IP and DID.

 

Example:

 

There is source IP A with its group A of DIDs, and there is also source IP B with its group B of DIDs.

 

The SBC must not admit traffic from IP A using a DID that is part of the group B.
